She added there was also fluorine leaking, but not so that it was noticeable.

“And our employees know what fluorine smells like,” Peters said.

Having two leaks within two weeks is a concern for Cameco, Peters said.

“We’re looking at ways to better monitor this type of equipment,” said Peters. “Both these incidents are being investigated by Cameco.”

She also reported earlier issues concerning elevated fenceline gamma at the Dorset Street East warehouse have now been resolved.

“Our investigation found that movement of drums within the building caused this increase,” Peters said. “We have changed the organization of drums, including those used as shielding, which has resulted in consistent monitoring results below 20 uSV/hr.”

She says that in the future, site radiation protection staff will be directly involved with the movement of materials at this site to prevent future reoccurrence of this type of increase.

These issues aside, Peters said Cameco’s emissions continue to be a small fraction of the regulatory limit and there were no “reportable” incidents in the first quarter of 2009.
